Former American Idol finalist Kellie Pickler is in a class of her own. The country singer appeared on ABC’s “Good Morning America Wednesday Sept. 5 2012 and told viewers, “Cancer does not discriminate.” At the time the 26-year-old singer was sporting a new haircut, had shaved off her beautiful platinum locks in support of her fiend Summer Holt Miller, who was recently diagnosed with breast cancer. It was an incredible display of friendship. Summer, who also shaved her head, added, “If this compels even one person to change their mentality toward waiting until the age of 40 for their mammogram, then it will be worth it.” Summer, who has started chemotherapy, is 36.

According to a press release on Pickler’s Facebook page, the two women have known each other since childhood and Kellie refers to Summer as her “sister.”

Kellie is known for changing up her do from time to time, going from a supershort pixie to long bob. She was also a spokesperson for the Sexy Hair line of hair styling products in 2009.

It’s one thing to cute your hair and another thing to go bald. Sources say it didn’t seem to faze Pickler: “I’m really not that apprehensive about shaving my head. It is hair, and it will grow back.”

The day before Pickler appearance on the morning talk show she tweeted, “It’s been a great life-changing day,” followed by another curious tweet: “Be sure to watch “Good Morning America” tomorrow morning (Sept 5th). You won’t want to miss this!!! ”

Now we know why. The County Kellie shared a video of her having her head shaved alongside friend.

Miller, aware of her family’s history of breast cancer, had always been super cautious with her self-examinations, but had the mother of two not been diligent with her doctor and requested a mammogram, the tumor detected in its early stage could have turned fatal. Miller recently underwent a double mastectomy and will begin chemotherapy this Thursday.

A behind-the-scenes video capturing the ladies’ cuts and truthful candor about Miller’s diagnosis and treatment will be shared on Athena® Water’s website,www.athenawater.com, and Athena® will make a monetary donation to the American Cancer Society in Miller’s honor. Athena® will contribute a minimum of $2 million to support breast cancer awareness, care, education and research by 2014.

“So many people feel helpless when a loved one is diagnosed with breast cancer,” says Athena CEO Dillon Schickli. “Athena gives everyone the chance to make a difference, with every bottle of water, 365 days of the year.”

Incidentally, this isn’t the first change Kellie has made to her hair since her “Idol” debut. Remember this look she sported briefly in 2009?

It doesn’t seem as though Pickler misses her tresses too much. “Today was one of the most incredible days of my life,” the singer wrote.
